4" Coils Sagging?

I have a 4" Rancho Suspension in mt '87. Not really happy with the ride (harsh) and am looking to swap out the springs for something softer. At the moment I get a little rubbing with the tires and am wondering how much these Ranchos have sagged or settled over the years of abuse.

For replacements I am looking at the Skyjackers Softride.

I would like to know if I could get some measurements from the top of TTB (where the bumpstop hits) to the bottom of frame for those of you who are running a 4" Rancho or Skyjacker lift? Mine vary a little side to side, do yours? Also how long have they been on your rig.

Other brand of 4" springs are also appreciated as well as any commentary about the ride quaility.

I did search and found some info about ride quality, but I am really after the dimensions, age, and brand of spring info.

Thought about it, but for a 4" coil it would be about $500. A little rich compared to the $160-$200 other brands.

If you get the 5.5" deaver and use the ranger lower retainer you end up with about 4.75" thats what i did. You do however loose the sway bar doing so. Could keep the sway bar if you dont have a front duel shock setup but your truck has the lower mounts for the shocks. Would take alittle fabbing but nothing way out there.

It's not custom if you bought it from a catalog!

JBfab, did you have any alignment issues?

Also, after you removed the swaybar, how does it handle on the road when you have to swerve around something? I know your wheelbase is longer, just curious?

With the adjustable 3.5 deg cams you shouldnt have any alignment issues. Its only 3/4" over four and thats not hard to tune in for an alignment. Yeah my wheel base is about 140" thats almost 12' so its a non issue with mine. I know alot of people say F the sway bar anyways.

I have 4inch rough country springs on the front of mine and the measurement from the frame to where the bump stop would hit is 8".My bumpstops are long gone though. I've had my springs on there for about 3 years and the ride is still pretty smooth.

I just checked the other side and its sitting at about 8 1/4" I am really the only passenger in the old girl though as the wife rarely goes wheeling with me. So I'm sagging a little too.
